一个基本程序里的少量错误,紧急求教修改!!
这个程序是个网球的记分牌,以前问过一次了,最后还有一点错误希望指正.
要求输入一串A,B和S.(例如AAABBBBAASAABBS)
A代表A队得到一分,B如此类推,S代表把当前的分数print一次.
具体是从A队开始轮流发球,哪队发球就一开始显示Team X to serve:
第二行显示当前是局数的比分,
第三行显示当前每局里的比分,
还有些细节在代码里有说明.
现在的问题是当我只输入S,也就是大家都没开始比赛的时候print的结果是正确的,但是如果我有输入A或者B的话分数不单没加而且不显示任何东西程序就终止了,问题出在哪?
求教!!!!

[解决办法]
if (ch== 'A ')
pa=pa+15;
game=game+1;
应该改为
if (ch== 'A ')
{
pa=pa+15;
game=game+1;
}
下面的一样的改法
————————————————
....
if (gameBw==6)
setb=setb+1;
} //这个 }放在后面
这一句的前面
return 0;
}
[解决办法]
while(scanf(%c,&ch)!=EOF) 改 while(scanf( "%c ",&ch)!=EOF)

这个是正确的程序，你自己跟你的核对一下，呵呵！
